BACKGROUND Field of Disclosure

The present disclosure relates to a server chassis, and in particular to a server chassis with a three-dimensional reinforcing pattern.

Description of Related Art

With the growth in cloud demand, enterprises urgently need to add a large number of server devices. In the high-density use of the server devices, multiple servers are stacked in each cabinet. Generally, each server is loaded with at least one mainboard module, one memory module, one cooling fan, a plurality of hard disk assemblies arranged in a row or a column, or other electronic components such as a function adapter card. In addition, each server is also provided with electronic components in the server according to the cloud demands, so as to challenge the loading limit of the server.

However, since the server is erected on the cabinet through both sides of a tray, an area between both sides of the tray that is not supported is suspended in the cabinet. Thus, when the tray of the server bears the foregoing load, it may easily cause a flat surface of the tray to be easily subjected to downward recession or bending deformation. Therefore, not only the load capacity of the tray is reduced, causing components of a lower server to be damaged, but also the smoothness of staff pulling the server is affected.

Therefore, how to develop a solution to improve the foregoing deficiencies and inconvenience is an important issue that relevant persons engaged in the industry are currently unable to delay.

DESCRIPTION OF THE EMBODIMENTS

Reference will now be made in detail to the present embodiments of the disclosure, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts. According to the embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the disclosure without departing from the scope or spirit of the disclosure.

Reference is now made to FIG. 1 and FIG. 2, in which FIG. 1 is a perspective view of a server chassis 10 placed on a rack 600 according to an embodiment of the disclosure, and FIG. 2 is a top view of the server chassis 10 of FIG. 1. As shown in FIG. 1 and FIG. 2, in this embodiment, the server chassis 10 is removably positioned on a rack 600, and the server chassis 10 includes a housing 100 and two support portions 130. The housing 100 has a U shape and includes a bottom plate 110 and two side walls 120. The bottom plate 110 has a loading surface 111 and a backside surface 112. The loading surface 111 is, for example, rectangular, and the side walls 120 are respectively connected to two opposite sides (e.g., long side edges) of the loading surface 111 and extend together in a same direction (such as a Z axis) such that there is a bending mark 121 between each of the side walls 120 and the loading surface 111. The bottom plate 110 and the two side walls 120 together define an accommodating space 122. The housing 100 can be used as a tray for carrying various electronic components (not shown in drawings) in a server so that the electronic components are accommodated in the accommodating space 122 and placed on the loading surface 111 of the bottom plate 110 so as to support and bear the weight of the electronic components through the loading surface 111. The support portions 130 are respectively located on one surface of the side walls 120 opposite to the accommodating space 122 and configured to be erected on the rack 600, so that the bottom plate 110 is suspended on the rack 600.

The bottom plate 110 further has a three-dimensional reinforcing pattern 200. The three-dimensional reinforcing pattern 200 is evenly distributed on the loading surface 111 (such as an XY plane) of the bottom plate 110, and is processed by a pattern die to be integrally formed on the loading surface 111 of the bottom plate 110 for reinforcing the structural strength of the bottom plate 110.

Therefore, through the foregoing structure, the evenly distributed three-dimensional reinforcing pattern 200 can strengthen the structural strength of the bottom plate 110, so that the server chassis 10 bearing a weight can slow down or even avoid a degree of downward recession or bending deformation. Therefore, not only the load capacity of the server chassis 10 is reduced, but also the chance of damage to components of another lower server can be reduced, thus ensuring the smoothness of staff pulling the server.

Specifically, as shown in FIG. 1 and FIG. 2, in this embodiment, the three-dimensional reinforcing pattern 200 is disposed on all of the loading surface 111 as much as possible, that is, a coverage area of the three-dimensional reinforcing pattern 200 is substantially expected to be close to the total area of the loading surface 111 of the bottom plate 110. For example, the coverage area of the three-dimensional reinforcing pattern 200 is at least greater than 90% of the total area of the loading surface 111 of the bottom plate 110. More specifically, the coverage area of the three-dimensional reinforcing pattern 200 accounts for 80%-100% of the total area of the loading surface 111 of the bottom plate 110, or even 90%-100%. It is noted that the coverage area of the three-dimensional reinforcing pattern 200 is the entire area included by the maximum outline of the three-dimensional reinforcing pattern 200, that is, the coverage area of the three-dimensional reinforcing pattern 200 includes gaps 201 between pattern textures.

However, the disclosure is not limited thereto. In other embodiments, the three-dimensional reinforcing pattern may not need to be disposed on the whole loading surface. For example, the three-dimensional reinforcing pattern is only located on a part of the loading surface or does not cover a centroid position of the loading surface. Moreover, in other embodiments, the disclosure is not limited to the connection of the side walls to two opposite short side edges of the loading surface.

However, the disclosure is not limited to this. In other embodiments, the three-dimensional reinforcing pattern may be disposed on the entire loading surface, that is, the coverage area of the three-dimensional reinforcing pattern is equal to the total area of the loading surface of the bottom plate; alternatively, the coverage area of the three-dimensional reinforcing pattern may be only 10% of the total area of the loading surface of the bottom plate.

More specifically, as shown in FIG. 1 and FIG. 2, the three-dimensional reinforcing pattern 200 is formed by a plurality of serial texture groups 210 side by side, and the serial texture groups 210 are parallel to each other. However, the serial texture groups 210 are not necessarily parallel to each other in the disclosure. Each of the serial texture groups 210 includes a plurality of spaced-apart texture patterns 220. The texture patterns 220 are regularly and sequentially reproduced on the loading surface 111 of the bottom plate 110 toward a linear axial direction E. For example, the linear axial direction E passes through the two bending marks 121 and is parallel to a short side edge of the loading surface 111 (such as an X axis). However, the disclosure is not limited to this. In other variations, the foregoing linear axial direction may also pass through the bending marks but is not parallel to the short side edge of the loading surface.

In the foregoing three-dimensional reinforcing pattern 200, any two successively adjacent texture patterns 220 of each of the serial texture groups 210 are continuously extended in a manner of overlapping front and rear portions, that is, the front/rear portions of any two successively adjacent texture patterns 220 of each of the serial texture groups 210 are continuous side by side. Therefore, the three-dimensional reinforcing pattern 200 can reinforce the structure of the bottom plate 110 under load and increase the load-bearing capacity.

For example, in the foregoing three-dimensional reinforcing pattern 200, each of the serial texture groups 210 includes a plurality of bent portions 230 and a plurality of oblique line groups 240. Each of the bent portions 230 is respectively wavy or S-shaped, and the bent portions 230 are jointly arranged into a single-column chain-type structure 231 along the linear axial direction E such that any two successively adjacent bent portions 230 are staggered side by side. More specifically, each of the bent portions 230 has a first concave arc portion 232 and a second concave arc portion 233 opposite to each other. The first concave arc portions 232 and the second concave arc portions 233 are sequentially arranged along the linear axial direction E. In any two successively adjacent bent portions 230 in each of the single-column chain-type structures 231, the first concave arc portion 232 of one bent portion 230 and the second concave arc portion 233 of the other bent portion 230 face each other and jointly define a common area 234. Each of the oblique line groups 240 is located in one of the common areas 234. The oblique line groups 240 each include a plurality of (such as three) side-by-side linear portions 241 parallel to each other, and a long axis direction 241L of each of the linear portions 241 is not parallel to the foregoing linear axis direction E, that is, the long axis direction 241L of each of the linear portions 241 intersects with the foregoing linear axis direction E. Long axis directions 241L and 242L of the linear portions 241 in any two adjacent single-column chain-type structures 231 are different, and intersect with each other.

It is noted that in this embodiment, the bent portions 230 in the same column are staggered side by side, which means that in any two successively adjacent bent portions 230 in the same column, the first concave arc portion 232 of one bent portion 230 and the second concave arc portion 233 of the other bent portion 230 are partially continuous side by side on a same hypothetical axis L, and the hypothetical axis L and the linear axial direction E are orthogonal to each other.

In addition, in this embodiment, each of the serial texture groups 210 further includes a plurality of first bent portions 250, a plurality of first oblique line portions 260, a plurality of second bent portions 270, and a plurality of second oblique line portions 280. The first bent portions 250 and the first oblique line portions 260 are jointly located on one side of the single-column chain-type structure 231, the first bent portions 250 are sequentially arranged at intervals according to the foregoing linear axial direction E, and each of the first oblique line portions 260 is located between any two successively adjacent first bent portions 250. The second bent portions 270 and the second oblique line portions 280 are jointly located on the other side of the single-column chain-type structure 231, the second bent portions 270 are sequentially arranged at intervals according to the foregoing linear axial direction E, and each of the second oblique line portions 280 is located between any two successively adjacent second bent portions 270. In addition, the first bent portions 250 and the second bent portions 270 are disposed on both sides of the single-column chain-type structure 231 in a mutually mirrored mode. The first oblique line portions 260 and the second oblique line portions 280 are disposed on both sides of the single-column chain-type structure 231 in a mutually mirrored mode.

FIG. 3A is a cross-sectional view taken along a line segment AA in FIG. 2. FIG. 3B is an enlarged view of a part M of FIG. 3A. As shown in FIG. 2 and FIG. 3A, when the three-dimensional reinforcing pattern 200 is being formed, a metal sheet is processed from a backside surface 112 of the metal sheet by using a pattern die, and then the metal sheet is subsequently bent out of the foregoing housing 100. The three-dimensional reinforcing pattern 200 is an embossed pattern 221 (FIG. 3B) of the loading surface 111 of the bottom plate 110, the embossed pattern 221 bulges toward a direction D of the accommodating space 122, that is, the backside surface 112 of the bottom plate 110 has a concave pattern 223 (FIG. 3B) corresponding to the embossed pattern 221. In the disclosure, the means of processing the metal sheet through the pattern die are not limited to processing through a stamping die or an embossing roller and other similar means.

It is noted that a maximum height 222 of the embossed pattern 221 is 0.5-0.8 mm. In other words, the embossed pattern 221 is only an embossed pattern of the bottom plate 110, and is not a convex hull or a convex pillar. Therefore, due to the limited height of the embossed pattern 221, not only the hardness of the bottom plate 110 can be improved, but also the maximum space of the bottom plate 110 can be effectively utilized.

FIG. 4A is a partial schematic view of a bottom plate 110A of a server chassis according to an embodiment of the disclosure. As shown in FIG. 2 and FIG. 4A, the bottom plate 110A of FIG. 4A is substantially the same as the bottom plate 110 of FIG. 2. One of the differences is that the bottom plate 110A further includes at least one reinforcing convex hull 500. The reinforcing convex hull 500 is formed on the loading surface 111 in a protruding mode. However, although an embossed pattern 221A is formed on the bottom plate 110A, the embossed pattern 221A is not formed on the reinforcing convex hull 500. Therefore, the reinforcing convex hull 500 can effectively reinforce the housing structure at a specific part.

FIG. 4B is a partial schematic view of a bottom plate 110B of a server chassis according to an embodiment of the disclosure. As shown in FIG. 4A and FIG. 4B, the bottom plate 110B of FIG. 4B is substantially the same as the bottom plate 110B of FIG. 4A. One of the differences is that an embossed pattern 221B is formed on the loading surface 111 of the bottom plate 110B, a reinforcing convex hull 501 of FIG. 4B is located in the coverage area of the embossed pattern 221B, and the embossed pattern 221B is located on a surface of the reinforcing convex hull 501. Therefore, in addition to the reinforcing effect of the embossed pattern 221B described above, the reinforcing convex hull 501 can more effectively provide a structural reinforcing function at a specific part.

It is noted that the foregoing embossed pattern is different from the reinforcing convex hull, and the reinforcing convex hull is much larger than the three-dimensional reinforcing pattern, and is, for example, 2 mm. However, the disclosure is not limited to this. Generally, the reinforcing convex hull 500 is formulated in accordance with industry practice standards. In addition, those with ordinary knowledge of the disclosure can determine whether to add a reinforcing convex hull to the server chassis according to requirements or restrictions in other embodiments.

FIG. 5 is a schematic view of a three-dimensional reinforcing pattern 300 according to an embodiment of the disclosure. As shown in FIG. 5, the three-dimensional reinforcing pattern 300 in FIG. 5 is different from the three-dimensional reinforcing pattern 200 in FIG. 1. Each serial texture group 301 includes a plurality of first arc portions 310 and a plurality of second arc portions 330. The first arc portions 310 are arranged at intervals along the foregoing linear axial direction E to be a first series 320. The second arc portions 330 are arranged at intervals along the linear axial direction E to be a second series 340. The second series 340 and the first series 320 of each of the serial texture groups 301 are parallel to each other. The second arc portions 330 of the second series 340 are in staggered alignment with the first arc portions 310 of the first series 320. More specifically, each of the first arc portions 310 has a single bracket shape, and each of the first arc portions 310 has a first recess 311. Each of the second arc portions 330 has a single bracket shape, and each of the second arc portions 330 has a second recess 331.
